Subject: FREE FOOD FOR ANIMAL SHELTERS
Hi,
For all you animal lovers. This is pretty simple.
Please tell ten friends to tell ten today! The Animal Rescue Site
is having trouble getting enough people to click on it daily to meet
their quota of getting free food donated every day to abused and
neglected animals.
It takes less than a minute to go to their site
and click on the purple box "fund food for animals" for free. This
doesn't cost you a thing.
Their corporate sponsors/advertisers use the number of daily visits to donate food to abandoned/neglected animals in
exchange for advertising.
Here's the web site! Pass it along to people you
know.
